Hello AAC community,
I am trying to build a PWM Fan Controller like this one but I can't get it to work. Instead my 555-Timer is getting really hot, the other components not. Have I shorted it somehow? I'll attach my circuit on a breadboard. The "original" circuit can be found on the overclockers site I linked or here.
(Haven't tried an other 555 yet)

Also, do you have a fan that will operate with less than 2 volts? It you are using an NE555 rather than the CMOS LMC555 the positive output looses two diode drops, making the maximum lightly loaded output only 1.8 volts.

It might be that the motor is drawing a lot of current. Try disconnecting the motor and see whether the '555 still gets hot.
